Downgrading ReadyNAS firmware from 6.10.x - Redux
I know this subject has been covered in the past, but almost all the articles are from many years ago. And none are helpful for my issue. I've been using my reliable ReadyNAS 102 for many years now. It's now been upgraded to 6.10.8. The problem I'm having is the throughput is only able to get to about 100 Mb/s. I know in the past, it used to be about 500Mb/s. I'm not sure when this started but I just noticed a month or so ago.
I've gone though everything I can think of, but nothing's worked. I have another thread here where I'm getting help working on that part, but in this thread I want to know more about the currently known pitfalls of trying to downgrade the firmware to see if that's playing a role. Another user responded to my other thread and said their throughput was near what I was getting in the past. So this may be a shot-in-the-dark.
So far I've been able to downgrade to 6.10.0, but not older, at least by the methods documented by Netgear or other posts. I'm also aware of some information that suggests that it's not possible due to changes in the bootloader.
I'd appreciate it greatly if anyone can shed more details or point me to more info on the Downgrading processes limits and methods. I'm at the point of considering chucking this one. And getting a non-Netgear system.
Again, thanks for any insights.

Because ARM based ReadyNAS use UBOOT to load the OS, they are far more fragile WRT OS downgrades than an Intel based system. As for the limits, they are officially that you can only go backwards beyond the first decimal place, which is as far as you've already gone. (6.10.x to 6.10.1 is OK, but not to 6.9.x).
I have never downgraded an ARM based system beyond the Netgear recommendation. I have done so on an Intel system, but always as a part of a factory default. USB recovery doesn't check the version, so that's one way to accomplish it. Another is to edit the file and give it a bogus version number that looks like an upgrade. But you are at your own risk as to potentially bricking the NAS. The reason for this being a part of a factory default is that it insures that there are no leftover configuration files from the previous version that are not backwards compatible, since most are not changed directly by an OS version change.
Sandshark.Thank you for the very useful info. It seems unwise to try to downgrade this any further.
Is there anything you can think of that I might do to figure out why my NAS is so slow? I've ssh'd into the NAS and used top to monitor the CPU usage and it's very high when using Windows Explorer to copy large files, about 90%.
I'm at a loss to figure this out.
Your NAS is slow because the 100 series are the least capable OS6 based ReadyNAS. Both the processor and RAM are limitations. I suppose it's possible that the upgrade to OS6.10.x used enough additional memory that everything slowed down. Do you have any apps running? Disabling them might help.
